They tend to open unless they are used, for example, on a door that only opens straight ahead. I bought for a small fridge so the doors are securely closed, they don't close. But I drilled a freon line and that's it. A few days ago I mounted a pet gate on the wall. It should be possible to move the gate to a different location and fixed wall hinges on the gate were not an option. So instead of just blocking my bulldog's access to the living area, I could move if I had to so he could. I also don't come into the kitchen if I have company or just need to avoid him. Basically blocking him halfway out of the house but still keeping him in the room so he doesn't feel left out. He gets excited and loves to jump on everyone. ππΌWhen the gate is pulled out of the wall, it will unlock. a little just at the ends where I have them just so that section stays on the wall (the extra sections don't really keep it in). But it holds when the dog pushes from the side it's on. So overall they did their job quite well. (Cable ties are only for breadboards, but they hold up pretty well.) I'll see if I can use two of the last three to replace a broken plastic latch on a toolbox. Maybe I'll update as soon as I get around to it if possible.
